What this study is about
The purpose of this study is to determine the effectiveness of mobile health applications in improving health outcomes in patients with overweight and obesity. This study will involve a 6-month long commitment where participants will be expected to use an mHealth app daily, weigh themselves and check their fasting blood glucose levels every morning.

Interventions
OTHER
Healthi
Healthi refers to the Healthi app, which is a mobile application for weight loss
Primary outcome measures
Effectiveness of mHealth apps at changing bodyweight assessed by bodyweight measurements over 6 months
Time frame: 3 months
Determine if the mhealth app is an effective weight loss modality compared to standard weight loss program (control) Outcome measure will be body weight in kg
Self-efficacy in weight management assessed by Weight Management and Nutrition Knowledge questionnaire
Time frame: 3 months
Compare and determine which intervention promotes self-efficacy in weight management. Reporting will be on a scale of 0-100, with higher scores indicating higher self-efficacy
Long-term change in diabetes via fasting blood glucose
Time frame: 3 months
Compare and determine which intervention elicits the most change towards diabetes via fasting blood glucose Outcome measure will be fasting blood glucose
Quality of Life after using mHealth apps assessed by World Health Organization Quality of Life BREF questionnaire
Time frame: 3 months
Comparing the two arms to determine which leads to greater quality of life (QOL) Measures will be reported on a scale of 1-5 across four domains. Scores will be converted to a scale of 0-100

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
